WINDOW-CLEANER.

Specification of Letters Patent.

Application filed December 14, 1916. SerialNo. 136,911.

To all whom it may concern:

Be it known that JOHN F. ZELBE/R, a sub ject of the Emperor of Austria, residing in the United States, in the city and State of New York, and LITTIQETON W. SWEETMAN, -a citizen of the United States, residing in the city and State of New York, have invented certain new and useful Improvement in Window-Cleaners, of which the following is a specification, reference being had therein to the accompanying drawings,

This invention is designed to facilitate the cleaning of windows, particularly under circumstances which render it inconvenient or impossible to have direct access to one side of the window. For instance, th'e invention is well adapted to'clean the rain, sleet and snow from the 'outersurface of the window of a locomotive, trolley car, or other railway vehicle, or from the window of an automobile, or the Windows of high buildings. In every instance the cleaning operation may be efiected by manipulating the device from the inside, and without opening the window.

- One adaptation of the invention is illus- -trated in the accompanying drawings in which:

Figure 1 is an inside elevation of the window sash and pane;

Fig. 2 is a sectional elevation thereof on the plane 2, 2 of Fig. 1 and looking from a .view point to the right thereof;

Fig. 3 is a right elevation. of the sash of, Fig. 1, with the right guard plate removed; and

Fig. 4 is a plan section of the pane-andE 0 that figure. Metallic scrapers 16 and 17 engage the inner and outer surfaces of the glass pane 5, and are U-shaped in cross-section so as 'to retain the rubber wipers 18 and 19 clenched within them. These scrapers are extended into thin plates 20 and 21 which follow around the surfaces of the vertical sash members 6 and enter slots formed between the vertical edges of these members and the guard channels 8 secured on. the

ends of said sash members by screws 9. These plates 20 and 21 may be formed, integrally with the scrapers and with weights 1 3 and 14' which slide inside the guard channels 8 and are clamped together by screws 12 and 15 to unite the opposite scrapers. A cord 11 is secured at its ends to the weight screws 12 and thence. extends upward inside the guard channels and thence through guide tubes 10 to the inner faces of the sash members 6 from which the cord depends in a loop which may be pulled by hand to raise both scrapers and thus simultaneously clean both sides of the pane. When the cord is released, the weight of the parts returns the scrapers to their lowermost position against the lower horizontal sash member 7. Manifestly both scrapers may be simultaneously worked by directly grasping either scraper. The sash members 6 and 7 together with the guard channels 8 constitute a neat, compact finished sash which may be suitably mounted in a window frame. l

The scope of the invention is pointed out in the following claim:

Window cleaning apparatus comprising scrapers adapted to fit closely against the window glass on opposite sides thereof and connected together around the edges of the sash, weights connected with the scrapers at the points where said scrapers are thus connected together, a cord extending from weight to weight and leading from the weights upward along the sash edges and thence'through guide holes to one face of the sash near itsupper end and thence depending in -a loop, and guard channels attached to opposite .edges of the sash and formed to inclose and guard the cord and the weights and allow entrance of the connetting ends of the scrapers, substantially as described. p In testimony whereof we have aflixed our signatures.

JOHN F. ZELBER. v LITTLETON W. SWEETMAN.
